  • slot 2 is a downlink slot
  • slot 1 and slot 3 are uplink slots
  • the terminal determines based on K1 that the downlink transmission slot corresponding to slot 3 is slot 2. Since there are two SPS PDSCH transmissions in slot 2, and the SPS PDSCH transmission with the configuration number of 2 is a repeated transmission, it is determined that the terminal cannot receive the SPS PDSCH with the configuration number of 1 due to a collision with the semi-statically configured uplink symbol in slot 1.
  • Case 2-1 if the SPS PDSCH transmission that collides with the semi-static uplink symbol needs to be excluded from the feedback codebook, then the HARQ-ACK feedback codebook corresponding to slot 3 only includes the corresponding feedback about the SPS PDSCH with the configuration number of 1 in slot 2, that is, there is 1 bit in the feedback codebook.
  • Case 2-2 if the SPS PDSCH transmission that collides with the semi-static uplink symbols does not need to be excluded from the feedback codebook, then the HARQ-ACK feedback codebook corresponding to slot 3 needs to include the corresponding feedback about the two SPS PDSCHs in slot 2, that is, there are two bits in the feedback codebook, where the first bit corresponds to the SPS PDSCH with the configuration number of 1 in slot 2, and the second bit corresponds to the SPS PDSCH with the configuration number of 2 in slot 2.
  • the last 3 symbols in slot 2 are uplink symbols and valid PUCCH resources exist, although the corresponding PDSCH transmission slot 1 can be found based on K1, and there is a valid SPS PDSCH transmission in slot 1 that can be received by the UE, that is, it does not collide with the semi-statically configured uplink symbols, nor does it overlap with other SPS PDSCH transmissions, the UE does not need to provide feedback about the SPS PDSCH transmission of slot 1 in slot 2. This is because the SPS PDSCH transmission with the configuration number of 2 in slot 1 is not the last transmission opportunity determined based on the configured quantity of repeated transmissions, so it will not be included in the feedback codebook of slot 2.
  • FIG. 5 is a schematic diagram of SPS PDSCH overlapping in embodiment 2.
  • the UE is configured with three SPS PDSCHs, wherein the configured quantity of repeated transmissions for the SPS PDSCH with a configuration number of 1 and the SPS PDSCH with a configuration number of 2 is 2, and the configured quantity of repeated transmissions for the SPS PDSCH with a configuration number of 3 is 4.
  • Both the SPS PDSCH with the configuration number of 1 and the SPS PDSCH with the configuration number of 2 are repeatedly transmitted twice in slot 3 and slot 4, and the SPS PDSCH with the configuration number of 3 is repeatedly transmitted four times in slots 1 to 4.
  • the UE only receives the SPS PDSCH with the configuration number of 1 in slot 3 and slot 4, and does not receive or demodulate the SPS PDSCH with the configuration number of 2 and the SPS PDSCH with the configuration number of 3.
  • slots 1 to 4 are downlink slots, and slot 5 is an uplink slot; the terminal determines based on K1 that the downlink transmission slot corresponding to slot 5 is slot 4. Since there are three SPS PDSCH transmissions in slot 4, all of which are repeated transmissions, it is determined that the terminal can receive the SPS PDSCH with the configuration number of 1 in slot 4; the SPS PDSCH with the configuration number of 2 cannot be received in slot 3, so the SPS PDSCH with the configuration number of 2 does not have a valid transmission opportunity; the SPS PDSCH with the configuration number of 3 cannot be received in slot 3, but can be received in slot 1 and slot 2, then the SPS PDSCH with the configuration number of 3 has valid transmission opportunities.
  • the HARQ-ACK feedback codebook corresponding to slot 5 needs to include the corresponding feedback about the SPS PDSCH with the configuration number of 1 and the SPS PDSCH with the configuration number of 3 in slot 4, that is, there are two bits in the feedback codebook, where the first bit corresponds to the SPS PDSCH with the configuration number of 1 (actually the SPS PDSCH with the configuration number of 1 received in slot 3 and slot 4), and the second bit corresponds to the SPS PDSCH with the configuration number of 3 (actually the SPS PDSCH with the configuration number of 3 received in slot 1 and slot 2).
